Anybody know much about A/C?

Well, the hobby shop at Beale does not allow anyone but their own mechanics to use their A/C filling and recovery system. They claim it's state law that only an ASE certified tech can use it, and shop policy that only the hired mechanics may use it. Jerks!

I have done some checking with the temp sliders, they are working fine. Any movement from the cool side starts bringing in warmer air from the heater core. There is no problem with the controls, but am now certain that I'm low on freon.

I'll try to get that remedied in the next day or two.
